ABSTRAK
Kualitas tidur memiliki peran penting dalam menjaga fungsi kognitif, khususnya
pengambilan keputusan, yang sangat dibutuhkan oleh mahasiswa kedokteran. Penelitian ini
bertujuan untuk menganalisis hubungan antara kualitas tidur dengan pengambilan keputusan
pada mahasiswa Program Studi Pendidikan Dokter Fakultas Kedokteran Universitas Syiah
Kuala angkatan 2022. Penelitian ini merupakan studi analitik kuantitatif dengan desain cross
sectional yang dilaksanakan pada Oktober–Desember 2025 dengan melibatkan 138
responden yang dipilih menggunakan teknik consecutive sampling. Kualitas tidur diukur
menggunakan kuesioner Pittsburgh Sleep Quality Index (PSQI), sedangkan pengambilan
keputusan dinilai menggunakan Decision Making Questionnaire Guide yang mencakup
dimensi naluriah, berprinsip, optimalisasi, resistensi sosial, keragu-raguan, kendali, dan
ketelitian. Analisis data dilakukan secara univariat dan bivariat menggunakan uji Chi-Square
dengan tingkat kemaknaan 95%. Hasil penelitian menunjukkan bahwa mayoritas responden
memiliki kualitas tidur buruk (66,7%). Terdapat hubungan yang signifikan antara kualitas
tidur dengan seluruh dimensi pengambilan keputusan, termasuk naluriah, berprinsip,
optimalisasi, resistensi sosial, keragu-raguan, kendali, dan ketelitian (p < 0,05). Mahasiswa
dengan kualitas tidur baik cenderung memiliki pengambilan keputusan yang lebih optimal
dan teliti dibandingkan mahasiswa dengan kualitas tidur buruk. Disimpulkan bahwa kualitas
tidur berhubungan secara signifikan dengan pengambilan keputusan pada mahasiswa
kedokteran, sehingga upaya peningkatan kualitas tidur perlu menjadi perhatian dalam
menunjang performa akademik dan profesional mahasiswa.

ABSTRACT Sleep quality plays an important role in maintaining cognitive functions, particularly decision-making, which is essential for medical students. This study aimed to analyze the relationship between sleep quality and decision-making among students of the Medical Education Program, Faculty of Medicine, Syiah Kuala University, class of 2022. This study was a quantitative analytic study with a cross-sectional design conducted from October to December 2025, involving 138 respondents selected using consecutive sampling. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while decisionmaking was assessed using the Decision Making Questionnaire Guide, which includes the dimensions of intuitive, principled, optimization, social resistance, indecisiveness, control, and thoroughness. Data analysis was performed using univariate and bivariate analyses with the Chi-Square test at a 95% confidence level. The results showed that the majority of respondents had poor sleep quality (66.7%). There was a significant relationship between sleep quality and all dimensions of decision-making, including intuitive, principled, optimization, social resistance, indecisiveness, control, and thoroughness (p < 0.05). Students with good sleep quality tended to demonstrate more optimal and thorough decision-making compared to those with poor sleep quality. In conclusion, sleep quality is significantly associated with decision-making among medical students; therefore, efforts to improve sleep quality should be considered to support students’ academic and professional performance.
